You could probably do it without custom backtesting at all. Try something along the lines of the following (untested):

Buy = ...;
BuyPrice = ...;

Bought = ExRemSpan(Buy, 5);
BoughtPrice = ValueWhen(Bought, BuyPrice);

X = ...; // Desired percent profit expressed as fraction e.g. 0.05
NormalSell = ...;
FailureSell = Ref(Bought, -5) && Close < BoughtPrice * (1 + X)

Sell = NormalSell OR FailureSell;
